Left 4 Dead 2 is the sequel to the best-selling and critically acclaimed cooperative multiplayer smash from Valve, creators of “Half-Life,” “Portal,” “Team Fortress” and “Counter-Strike.” Introducing melee weapons and new enemies to the original’s award-winning gameplay, L4D2 casts players as one of four new “Survivors” battling zombie hordes as they travel from Savannah, Ga., through New Orleans’ French Quarter.

The spot, created in collaboration by Valve and GameStop, highlights the exclusive in-game melee weapon (American baseball bat) offered to those who pre-order the game at GameStop (0:40) - you must be 17 or older to download or view it
